MOV to MP4 Converter
Convert MOV videos from iPhones, iPads and QuickTime to MP4. Most MOV files already contain H.264 or HEVC video and AAC audio, so the default "Fast" mode just repackages them in seconds with no quality loss.

MOV vs MP4 — what actually changes
MOV (QuickTime) and MP4 are closely related containers, and iPhone videos use the same H.264/HEVC video and AAC audio in both. Converting is therefore usually a remux: the streams are copied into an MP4 box unchanged. It takes seconds even for long videos, and the quality stays the same. Windows, Android, WhatsApp and web uploads handle MP4 more reliably than MOV.
One exception: HEVC (H.265) videos from newer iPhones stay HEVC inside the MP4. Most devices play that, but some older Windows PCs and websites don't. If the MP4 doesn't play somewhere, convert again with quality High to re-encode to H.264, which plays everywhere.
